By default, all sequences start out in the GTK_EVENT_SEQUENCE_NONE state, sequences in this state trigger the gesture event handler, but event propagation will continue unstopped by gestures."
(not sure if this is actually the case.)
Hi everyone,I am a GSoC student participating this year from wxWidgets. The aim of my project is to implement an API for 3 multi-touch gestures (pan, zoom and rotate) for 3 major platforms (windows, linux and macOS). Understanding the features provided by windows and macOS wasn't hard at all (even though I was not familiar with Win32 and Cocoa). On gtk+, I find it difficult to understand the gesture APISo, my question is where do I need to look to implement an API for the above mentioned gestures in gtk+ ?I looked at the "gestures and event handling guide" by gtk but that didn't help me much. Also, there are few questions that I want to ask someone who is familiar with gestures in gtk+ and willing to help me.1> There is something called the expected pan gesture direction that we have to set before receiving the pan gesture. Now, what if we want to receive it for all 4 directions ?3> Is it possible to know the position of pan gesture i.e. position of the finger in action ?2> Is it possible to get the center of the zoom gesture ?3> After we receive some gesture , Is it possible to know if it a starting of the gesture ?I would really feel relieved if anyone provides me any help. Thank you in advance.- prashant
